bimanual_blue_block_handover_2

This dataset is a TsFile conversion of the LeRobot dataset Batonchegg/bimanual_blue_block_handover_2. The original dataset was created using LeRobot and is licensed under Apache 2.0.

Modalities: Time-series. The converted repository stores numeric robot frame data in Apache TsFile format. Source videos remain in the original Hugging Face dataset under its videos/ tree: https://huggingface.co/datasets/Batonchegg/bimanual_blue_block_handover_2/tree/main/videos

Dataset Scale

  • Source robot type: bi_so101_follower
  • Episodes: 30
  • Frames / TsFile rows: 18,613
  • Tasks: 1
  • Source videos: 90, not mirrored in this repository
  • Sampling rate: 30 FPS
  • Output file: data/bimanual_blue_block_handover_2.tsfile
  • TsFile table: bimanual_blue_block_handover_2

Schema

Time is an INT64 millisecond timestamp synthesized from the source timestamp column as round(timestamp * 1000). Time restarts per episode.

TAG columns:

  • episode_index
  • task_index

FIELD columns:

  • frame_index
  • sample_index, renamed from source index
  • action_0 through action_11, flattened from source action
  • observation_state_0 through observation_state_11, flattened from source observation.state

Conversion Notes

The source timestamp column is dropped because it is represented by TsFile Time in milliseconds and equals Time / 1000 seconds. frame_index is kept.

Vector columns preserve the full source feature name with . replaced by _ and the element index appended. Values are stored as single-precision FLOAT.

The source video features observation.images.wrist_right, observation.images.wrist_left, and observation.images.realsense_top are not converted to TsFile and are not uploaded here. The converted meta/info.json keeps the original video path and records the TsFile conversion metadata.
